The contacting surfaces 95 at 1 and a crank-axle therefor at 2. A side of the saddle and the slide-plate are correbar of the cultivator-frame is shown at 3, a spondingly corrugated. beam at 4, a vertical shaft extension of the At the front part of the frame is a transbeain at 5, a beam-supporting rock-arm at G, verse rod or shaft 12, on which is mounted a a pendulous connecting-rod at 29, and a seat sleeve 13. A collar 14 is fastened onto the roo 5o at 7. A saddle il0 is fixed onto the uppersursleeve. It extends above the shaft 12, and it face of the upper horizontal extension or is bored from front to back through such up* ward extension. Lugs 16 extend laterally from the upward extension 15 of the collar. A sleeve 17 forms a vertical pivot for the forward extension 5 of the cultivator-beam. It has a Astud 19, which extends through the Afront-to-back bore of the collar, and it has lugs 18, which coincide with lugs 16 of the collar when the sleeve is in a vertical position. The front wall of the sleeve 17 is recessed at 2l, as shown in Fi g. 3. A bolt 2O extends through stud 19 with its head flush with the inner surface of the recess. A collar 23 is set into the recess with its bore in line with the bore of the sleeve, and when the vertical shaft 5 of the beam is inserted through the sleeve and the collar therein to a proper extent a setscrew 25 in the collar is made to engage the extension of the beam and hold it against upand-down motion in the sleeve. The collar cannot move up and down in the sleeve, and the extension 5 cannot move up and down in the collar when the set-screw 25 is set; but both the extension and the collar may swing sidewise to a considerable degree in their bearings in the sleeve. The stud 19 forms a horizontal pivot on which the beam may rock from side to side, and the. bolt 20, with its securingnut, holds the stud in the collar. When it is desired to swing the beam from side to side in a horizontal plane, the lugs 18 are secured to lugs 16 by bolts 22, and the pivot 19 is thereby locked or rendered ineffective. The sleeve 17 will then maintain a vertical position, and the extension 5 will rock in the sleeve as the beam swings horizontally. When it is desired to rock the beam with a pendulous motion, the lugs 16 are disconnected from the lugs 18 and the beam is rocked with the horizontal stud 19 for a pivot, while the shovels rise as they travel away from the center of the swing and descend as they swing under a line drawn through the horizontal pivot.

To facilitate the change in the movement of the beam, as hereinbefore described, the pendulous beam-sustaining rod 29 is connected with the beam by a pivotal joint that may be locked to compel the beam to rock on pivot 19. This coupling is shown in Figs. 1, 6, and 7, and its construction is as follows:

' A sleeve 26 is held crosswise of the beam 4 locked against pendulous swing on the horizontal pivot, the lugs 27 are disconnected from arms 32, and the rod rocks on trunnions 34 and 34a while the beam swings horizontally; but when the beam is permitted to swing on pivot 19 the arms 32 are fastened to the lugs by bolts 2S, and the beam and its shovels are forced to partake of the pendulous motion of rod 29. The hanger 30 is made in two parts, which are clamped onto the rod 29 by a bolt 33, and one trunnion of sleeve 26 is engaged by an extension 31 on onepart of the hanger, while the other truunion is engaged by an extension 31a on the other part of the hanger.

In describing the invention only one beam and adjuncts thereof have been described; but it will be understood that a plurality of beams are used in a modern cultivator and that one operates like another.y

I claim- 1. In a convertible horizontal pivot and vertical pivot for the front end of a cultivatorbeam, the combination of a cross-shaft on the front end of the cultivator-frame, a collar on the cross-shaft having an extension bored from front to back, a vertical sleevein which a vertical extension of the beam journals, a stud on the sleeve journaled in the front-toback bore of the collar and means for holding the stud from turning in its bearing, substantially as described.

2. In a convertible horizontal pivot and vertical pivot for the front end of a cultivatorbeam, the combination of a cross-shaft on the front end of the cultivator-frame, a collar on the cross-shaft' having an upward extension bored from front to back, a sleeve in front of the shaft, forming a bearing for a vertical eX- tension of the beam, a stud on-the sleeve journaled in the front-to-back bore of the collar, lugs on the collar, lugs on the sleeve coinciding with theY lugs on the collar when the sleeve is vertical and means :for fastening the lugs of the sleeve to lugs of the collar, substantially as described.

3. In a convertible horizontal pivot and vertical pivot for the front end of a cultivatorbeam, the combination of a cross-shaft on the front end of the cultivator-frame, a collar on the cross-shaft having an upward extension bored from front to back, a sleeve in front of the shaft cut away in one of its sides and having a stud journaled in the front-to-back bore of the collar, a clamp-collar in the cut-away part of the sleeve holding a vertical extension of the cultivator-beam, and means preventing the stud of the sleeve from turning in the collar on the cross-shaft, substantially as described.

4. In a cultivator, the combination of a beam, a horizontal strut-sleeve fastened between members of the beam, a pendulous rod for supporting the beam, a hanger on the lower end of the rod straddling the strutsleeve and connecting pivotally therewith between the ends thereof, lugs on the strutsleeve off the center thereof, arms on the hanger corresponding with the lugs on the sleeve, and means for fastening the arms to the lugs, substantially as described.
